In amyotrophic lateral sclerosis (ALS), neighborhood may be everything, if a new study in mouse models of the disease holds true for patients.
ALS, or Lou Gehrigs disease, brings about a gradual death of the motor neurons that activate muscles. Paralysis follows. But according to work described today in the journal Science, the cells that are next to motor neurons -- but arent themselves nerve cells -- can play a major role in advancing or limiting the disease.
"What weve been given is a new principle for extending survival or, perhaps, overcoming ALS, based on how many healthy cells surround an ailing motor nerve cell," says Don Cleveland, Ph.D., a scientist with The Packard Center for ALS Research at Johns Hopkins and, with Larry Goldstein, Ph.D., co-leader of the research team. "All this has great implications for stem cell therapy," he adds. "We now believe delivery of normal, non-neuronal cells to spinal cords could be completely protective, even without replacement of a single motor neuron."

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
